I photographed two Auchenoglanis that I would really like identified. The first one (bright picture) in a French aquarium last week. I believe it was signed as Auchenoglanis biscutatus, but I don't think it looks exactly like it. The second one (darker picture) was photographed at an importer that got it as Auchenoglanis senegali. It doesn't seems to match either, but I assume it comes from the same area as senegali, as it was a direct import. I think both animals look very much alike and match what I read on Aquarium Glazer under the name of Auchenoglanis sp. Niger, a still undescribed species. But I have seen other suggestions, like Auchenoglanis cf. occidentalis Volta. I need an expert on this matter!

Many thanks in advance!

I don't consider myself an expert at all. I have been working on a video for my channel on the species ID of the Auchenoglanis in earnest, having collected and analyzed couple hundred or more photos.

I have been growing out 7 Auchenoglanis myself for the last 6 years - 2 are Congo/wittei, 2 are Auchenoglanis "Bouche", 2 are "Volta" male and female, and 1 is Niger, perhaps the unknown species you are mentioning. I've had biscutatus before as well.

To my eye, these both fish look like what is called in the trade Auchenoglanis sp. "Volta".

I plan to publish the video soon, perhaps in 1-2 weeks, and will create a thread on here and on Monster Fish Keepers forum for discussion of the video and input from peers.

Thank you very much for the information! I'm looking forward to see your video!

I've published the video.
